Asynchronous Webservice EndInvoke Gets MissingMemberException

[JFritzler]

I am using the WSDL generated webservice class in a asp.net project to call an asynchronous webserivce and then do something when it completes.

~one~ of my web services doesn't work, here is what I have
One aspx page starts the call...

Dim mAsyncResult As IAsyncResult = mMyWebService.BeginMyMethod(blnIgnoreUnknownCodes, False, strMessage, True, Nothing, Nothing)

Session("ProcessStarted&quot=mAsyncResult
Session("MyWebService&quot =mMyWebService

and another ends it...

sub Page_Load
mAsyncResult = Session("ProcessStarted&quot
mMyWebService = Session("MyWebService&quot
If mMyWebService.IsCompleted Then
Dim result As Boolean
result = mMyWebService.EndMyMethod(mAsyncResult, strMessage) ' *****
End If
end sub

They both have member objects of the same class

The problem is that I get a MissingMemberException on the line with *****

Any ideas?
Thanks in adv

I found my problem.
I added a parameter to the BL and the method call in the *asmx, but forgot to put it in the actual CALL to the BL method in the asmx method body.

Oops
